Prefers vegetated habitats. Feeding habits overlap considerably with the sharptooth catfish. Important foods are mollusks, terrestrial and aquatic insects, insect larvae, shrimps, grain, crabs and fish (Ref. 4967, 78218). Feeds on snails (Ref. 5595). Hard-shelled foods such as mussels are crushed before they are swallowed. Breeds during the summer rainy season. May live for 5-6 years (Ref. 7248). Also caught with drawnets (Ref. 4967).

It is distinguished from Clarias gariepinus by having a short adipose fin behind the rayed dorsal and an ovoid vomerine toothplate with granular or blunt teeth (Ref. 52193).Description: Dorsal fin with 56-62 rays; anal fin with 50-58 rays; pectoral spines barbed along outer edge only (Ref. 52193). Gill rakers short and widely spaced, 18-32 on first gill arch; accessory suprabranchial airbreathing organ well developed (Ref. 52193).Colouration: Colour variable, grey or dark brown, often marbled, with cream or whitish underside to head and abdomen (Ref. 52193).
